Toall whom it may concern:

Be it known that l, O'rro J. LAUTERBACI-I, a citizen of the United States, residing at New Orleans, in the parish. of Orleans and State of Louisiana, have invented certain new and useful Improvements in Ink-1iaving Devices for Cotton-Printing Machines;

and I do declare the following to be a nun clear, and exact description of the invention, such as will enable others skilled in the art :to which it appertains to make and use the same. y p

This invention relates to an improved scraper for use in connection with the ink- Well of a cotton printing press and one object of the invention is to provide a scraper so constructed that it may be connected with the ink-well and positioned in operative relation to the feed roller and serve to scrape lint, thick ink and other matter ofi" of the feed roller and thus prevent the lint and other matter from working back into the ink placed in the ink-well. Tn presses for printing cotton, burlap and other fabric, the inking-rollers gather lint from the fabric and this lintis passed-from one roller to another until it finally reaches the inking roller which serves to feed ink out or the ink-well. When this lint becomes mixed with the ink in the ink-well, the ink in the ink-well is spoiled and the ink-well becomes choked so that the ink will. not properly ieed out of the ink-well. By providingthe improved scraper, the lint can be scraped oil of the roller and thus the ink in the well be kept clean and prevented from being spoiled.

1 Another object of the invention is to provide a scraper which'can be easily connected 1 with the side walls of an inlcwell above the p 1 feeding roller with the scraping blade extending" downwardly and engaging the feeding roller.

Another object of the invention is to provide a scraper which will have a very simple construction and which can be cheaply produced and easily put in place.

rier bar in place upon the i11l well.

This invention is illustrated in the accompanying" drawings, wherein Figure 1 is a perspective view showing the scraper in use. i I

Figure 2 is transverse sectional view through the scraper and feeding roller of an ink-well.

Figure 3 is a perspective view of the improved scraper.

This scraper is to be used in connection. with the ink-well 1 or a cotton printing press and isintended to scrape lint from the ink feeding roller 2. As previously explained. this lint is taken from the cotton which is being printed and is transferred across a series of rollers to the roller 2. One of these rollers is shown and indicated by the numeral 3. The press structure has not been shown since the inventionis only applied to the ink-well 1 and the device can be used in connection with any inkabove theroller 2 and has its end portions provided with openings 6 to receive fastener bolts 7 which serve to secure the cap}; scraping blade 8 which is preferably formed of sheet metal extends below the carrier bar 5 as shown clearly in Figs. 2 and 3 and as shown in 2 hasits free edge enthe face oi? the roller 2. From an inspection of this Fig. 2, it will be readily seen that as the roller turns in the direction indicated by the arrow, the scraper blade 8 will serve to. scrape the surface of the roller and effectively remove from this roller 1 any lint, thick ink or other matter which i may have accumulated upon the roller. By having the carrier bar 5 secured by bolts 7, these bolts may be removed and the scraper thus easily and quickly removed when it is desired to clean or repair the same. It will be further noted that with the construction shown, the scraper blade 8 can be easily removed and a new one put in place When necessary. It will also be noted that the scraper is so constructed that it can be readily applied to an ink Well of a conventional construction and therefore can be readily applied to ink-Wells already installed.

I claim:

- The combination With an ink-Well having side Walls, and a feeding roller rotatably mounted between the side Walls, of a lint Lee-3 385 remover having a carrier bar reinovaibly secured. upon the side walls and extending across the ink Well and a vertically disposed scraper blade -formed separate from said bar and secured to one side of the carrier bar and extending beneath the carrier bar for engagin the face of the feeding roller.

in testimony whereof I have hereunto set my hand.

OTTO J. LAUTERBACH.
